Vtwin Alternative

[racie35]

I'd love to see your twin Predators squeezed into a Whizzer Ambassador frame.

I don't think it'll fit...one 212 does okay though...I did that.

That sounds quite aggressive.

This is the racing version of the concept, it sounds very much like there is almost no flywheel mass.

What a sound!

Zenoah makes a cool 66cc opposed twin similar to that Wooler engine, mounted up to a 90 degree transmission it would make a neat mini BMW, albiet for way too much money! lol

I think that twin will be a very fun and economical way to fit a twin to a small motorcycle A.G., great work!

Interesting. Do you have a pic or link for the Zenoah? I have never found anything remotely like the Wooler.

Looks like fun, bet it's expensive though.

There are a few companies making flat twin 2 strokes, even flat 4s. Depending how big you want to go, you can even use microlight/drone engines:

 

[Theon]

wow!
I want a flat twin, surely someone could make a set of cases and a crank for two HT barrels. Even a couple of 49cc pocket bike jugs?

Briggs also mad some flat twins in lawn tractors 12-16 hp. Most were vertical but some were horzontal Toro for one............Curt

There are lots of flat twins out there.

Nothing close to the 4 cylinder Wooler design however

Fox is making a nice brute of a flat twin 2 stroke - 200 cc's

Expensive, but the R/C crowd seems to have money to burn.

Quite a clever design.

This is a opposed twin build that I just started. I was going to jack shaft it to the crank and use the three speed drive but have thought better of that. This engine should have enough power for the speed that a lightweight tire can handel. Instead I'll just run a belt drive and save the 3 speed for peddling.

I am also working on a vee twin engine like so many others are.

KOOOOOL what is the engine off of...........Curt

It is an old tecumseh twin. they made them for a few different bicycles but also used them on a lawnmower for a short time. 50's 60's.
Picked it up cheap on e-bay. I'll start a thread when I get further along. Got tired of seeing the engine sitting around.

 

[Intrepid Wheelwoman]

That is a really great engine. I'm going to be very interested to see what you will do with it.

 

[curtisfox]

I to have to watch this. It looks a lot like my old Monark twin i had back in the 50's.........Curt

Yet another simply beautiful device.
